Understanding the UV Index is crucial for residents of Baker City, as it serves as a vital tool in promoting skin health and preventing sunburn. With its characteristic Csb climate, Baker City experiences varying UV levels throughout the day, peaking at an index of 10 between noon and 2 PM. By being aware of these levels, you can enjoy the outdoors while effectively protecting your skin from potential harm. Whether you plan a leisurely afternoon in the sun or engage in outdoor activities, knowing the UV Index can make a significant difference in your overall health and well-being.
Today’s UV Index tells a compelling story of sun intensity throughout the day. Starting with a gentle maximum of 1 at 7:00 AM, the index gradually climbs, reaching 2 by 8:00 AM and 4 by 9:00 AM. As the sun rises higher, the UV exposure spikes, peaking at a notable 10 from 12:00 PM to 2:00 PM—a time when sun protection is essential.
